Scapular dyskinesis is often present in patients with shoulder and neck pain conditions. These patients frequently show a dysbalance between their upward rotators: upper trapezius (UT) and serratus anterior (SA) and downward rotators: levator scapulae (LS), rhomboid major (RM) of the scapula. The "shrug"-exercise has been prescribed in rehabilitation programmes to improve the upward rotation of the scapula. This study revealed that activity levels of the medial scapular muscles depend upon the specific shoulder position while performing the shrug and retraction exercises and showed the lowest activation during the "shrug overhead" exercise.
